Tropical Storm Danny Discussion 1








We have a new Tropical Storm and his name is Danny, he is currently moving in a WNW/NW direction heading toward the US.
Track

The models have been all over the place on this, we have the ECMWF/GGEM/UKMET/NOGAPS/GFDL heading for a Coastal storm and maybe even getting inland while we have the GFS/HRWF on the east side. The average of the models have this going near cape hatteras, then moving NNE/NE going near the coast.

Strengh

Models have this as a Tropical Storm or a Category 1 Hurricane at maximum speed.
I am predicting that this will be a coastal hugger.
Here are the percentages of a situation.
Mainly off coast:1 or 2 lanfalls:60%
Mainly inland:40%
Comments would be appreciated.


Danny is Born

Hi, its Junior Met Ryan with an update on Invest 92L. The invest had jumped right to a tropical storm with winds of 45mph. the storm is moving to the WNW at 1mph and its estimated central pressure minimum is 1009mb. Here is the forecasted track from the NHC. Expect updates from Chris, Nick, and I later on this storm. I may have my brief out late tonight. Stay tuned, and here is the NHC track image:

Invest 92 Potential Impacts


More detailed discussion will be made either later today or tomorrow, remember that this could go anywhere from OTS to west of the major cities ATM.

Saturday 0z Bill Discussion




Final Bill Discussion


Hurricane Bill has weakened to a Category 2 at the moment and is currently moving Northwest, 345 degrees at 20mph. 11pm location was 31.0N and 67.5, Hurricane Bill is expected to move in a northward direction until getting closer to cape cod where it then will turn NE away from land, models are basically done trending at the time being.
Since I have explained the factors and forecasts multiple times, I will just skip to the forecast, this should move northward until around 40 north when this moves northeast, about 300-500 miles from land maybe a landfall in canada, strengh will be at a low Hurricane level.
Comments would be appreciated.

Friday 0z Bill Discussion




Hurricane Bill continues as a category 3 storm and is moving Northwest at 18mph, this should continue for about 12-36 more hours until we get more of a NNW/N turn. The models and forecasts have generally stopped trending as Bill is on track with current forecast and model guidance.
Over the last 24 hours, Bill has moved on a Northwest course, on track with the current guidance. Current models are showing a northwest track for about 24 more hours and then will turn more NNW/N and get to near 70w before starting to turn NNE/NE at 35N to 40N not to far from cape cod, mainly 100-400 miles away. The UKMET, and NOGAPS have been constently showing a further west solution with them coming near 100 miles from the cape while models like the NAM and ECM are showing this near 400 miles away from it. So we still don't have full model agreement and likely models will eventually stay, move further west or further east. Also models are showing the rather strong subropical ridge, a US neutral/negatively tilted trough, and a cold front, these all change the places of the models and their affectance. For strengh, most models are showing a category 3/4 max range with low shear in the area will most likely strenghen this once more.
Now for my forecast, I am forecasting that this Northwest movement will continue for another 12-36 hours before it gets closer to the trough and will start turning NNW/N eventually riding its neutral/negative tilt until somewhere around 35N and 70W when the steering and cold front cause this to start to move NNE/NE most likely staying in the sea about 100-300 miles from cape cod before moving toward the eastern canada area and into the northern atlantic. This will be running into the upper level low and won't be effected that much by the subtropical ridge and the trough and cold front will be the ones affecting its position, for my best forecasts and models of choice, I would choose the NHC, GFS, and ECMWF as I beleive they have the best charecteristics.
Here is what I am predicting for percentages of where this goes.
Out to sea, over 300 miles from land:10%
Middle Path, 100-300 miles from land:70%
West Path, under 100 miles from land:20%
For the strength of Bill, it is currently a 125mph Category 3 Hurricane, and I am expecting this to most likely strenghen back up to a category 4 storm with low shear. Once again, if I has to take a guess, I would have to say the strongest wind speed will be in the 140-150 mph zone. As this moves further north, the cooler water temperatures will help weaken this once we get above around 35N, this should be a Weak Hurricane, about a category 1 or 2 once this has its closest approach to land. You do not want to be in this storm with these strong winds, so get ready for it if needed.
Even though this will most likely miss land, this should cause high waves and rip currents across most of the Mid Atlantic and Northeast coastal areas, which some are already getting affected by this, if you go to the beach, make sure you know what you are doing. There may also be some rain and wind with this, especially in the Southern and Eastern New England areas.
So although I am not expecting a landfall with this, I will warn that we are not out of the woods for major effects on the eastern seabord or Bermuda, I still warn that you folks should watch this storm closely and take precautionary action if needed as this may not be done changing in forecasts and models as it is possible that the storm, subtropical ridge, US trough, and cold front will change position, strengh, and speed. So once again, I am expecting this to get only about 100-300 miles from land, so effect is likely.
Comments would be appreciated.

Thursday 0z Bill Discussion




Hurricane Bill is continuing to strenghen and move North West, the current wind speed is 135mph Category 4 and is moving Northwest, about 305 degrees at 17mph. The model and forecast guidance overall is still slightly moving further west as the northward turn is not coming to friction when it was modeled to.


The latest models are still generally shifting west, most runs now have this going west of bermuda and within effecting distance of Southern New England, some models like the GFS Ensembles, UKMET, and NOGAPS come close to the cape area and come near 100 miles away giving them rain and wind. Otherwise, the rest have this going further east but still west enough for some effect. The shift west has been caused by a speedier than progged storm, a further south storm with a stronger subtropical ridge, and a slower than expected United States trough, which should become Neutral/Negative and ride this up the coast Northwest then Northward until the front gets to it and pushes it more northeastward. Once again, it is not just forecasting time, it is nowcasting time as well with current observations.

For my forecast, I am expecting this to continue on a NW motion for another 24-48 hours possibly, then it will get closer to the Negatively tilted trough and turn Northward, by then we should be about 70w with the storm, and then once it gets closer to the incoming cold front, this will turn it Northeast racing toward near Southern New England, most likely getting only 100-200 miles away. If the trough slows down, this could be a more coastal situation and run up near the coast or an OTS situation if the trough speeds up, you can see my map above with the black line representing the most likely path. Here is what I am expecting for percentages of a solution.

Out To Sea, near or east of bermuda, little to no effect:10%
Middle Path, goes about 100-200 miles from the CAPE, decent effect especially SNE:60%
Coastal Path, landfall, major effects, especially on SNE:30%

Now for strengh, it is currently a Category 4 135mph Hurricane, with the current observations, models and forecasts, they say that this will peak at Category 4/5 strengh, if I had take a guess, I would say the top wind would be about 150mph with this. If anyone gets hit by this, you will have to prepare for the strong winds.

Now how this verifies comes down to the speed, location and strengh of Bill, the location and strengh of the ridge, and the location and speed of the Trough and Cold Front.

I still warn that folks in the Mid Atlantic and Northeast, with Bermuda should be watching this one closely and take precautionary action if needed, this storm is stronger than some think and it may cause threats to structures and people, so I advise watch this storm as the track may change a lot more.

Comments would be appreciated.

Wednesday 0z Bill Discussion




I have been following the latest observations of the Hurricane and they are showing a WNW/NW movement at the moment, this hurricane is also still strenghening rather quickly.

Once again, the reason why we are continuing the WNW/NW movement instead of the more NW/NNW/N movement is because of the underestimated speed of the storm, the strengh of the subtropical ridge, and the speed and strengh of the trough in the United States. Most models have begun the Northwest/North turn to early and hence since then, most of them have trended at least some west, for example 12z Nogaps, and 12z ECM are not far from the coast, take them for granted. As of right now, this is not just forecasting time, this is nowcasting time too, observing the storm, wind speed, track, and location.

I am forecasting this WNW/NW direction to last for 24-48 more hours before we turn more northward, I am expecting this to get as far west as about 70W off Cape Hatteras and then ride North/Northeast most likely affecting SNE before turning more eastward, though there is still time for this to change, this could go closer to bermuda or closer to the US coast depending on Bill's path, and the strengh and location of the subtropical ridge and trough. You can see my map above, once again the black line equals the most likely possibility.

Here is what I am predicting for the percentages of the situation.

Early Curve, Bermuda Hit or East of Bermuda:10%
Expected Time Of Curve, Between Bermuda and US, Effects in SNE:60%
Later Curve,Coastal Scraper and SNE landfall, Mid Atlantic and Northeast Affect:30%

Overall, In my opinion, most of the Mid Atlantic and Northeast should get affected by at least higher waves, I insist on folks on the Eastern Seaboard and Bermuda should watch this closely and take action if needed.

Next update will be 0z Thursday.

Comments would be appreciated.

Second Forecast On Bill




Over the last 36 hours, Bill has went through good strenghening, we are now at a Category 2 Hurricane.

Over the last 24 hours, I have noticed the faster than forecasted speed of bill, which is giving it more time to move Westward before the trough gets to it while a ridge stays north. This evening's steering currents are helpful of a temporary westward movement.


Now for the track, I am expecting this to move westward for potentially up to 12 hours, before it starts turning WNW, in 24-36 hours, depending on the speed of the storm and trough, should start turning NW, and then should start heading N, most likely west of Bermuda, and then should move back out to sea. The reason I am using should is that if ths storm can move fast and south enough, this MAY go through the carribean area and into the GOM potentially. The strength of this should max out at category 3/4 strength. I have revised my map which you can see above, black line equals the best chance for a track in my opinion.


Here is the percentages for the situations.


Out to sea, east of Bermuda:5%

Between Bermuda and America:50%

East Coast Landfall/Effect:30%

Gulf Of Mexico:15%


As of right now, everyone from Florida to Maine should watch this one closely in the next coming days.


Comments would be appreciated.


Tropical Outlook (Bill)

Hi, it is Ryan with an update on Hurricane Bill.

As of 5PM AST
Winds: 90mph
Gusts: 105mph
Minimum Central Pressure: 969mb
Movement: WNW 16mph

I will have other info if any land is threatened.

I think the models are surely trending west. The weakness as mentioned was overestimated. The trough is quite deep in the GL and the trough axis, which with the 18z had the neutral at 108 to the slightest bit negative to me at 126. I am a good bit confident that the trough is not negative enough and therefore deep enough to prevent a strong shunting and recurve of the storm like TWC and the NHC are predicting somewhat. I think anyone from Cape Hatteras to Nova Scotia needs to keep their eyes peeled on this storm.

My software isn't working so I don't have the images. Computer=suckish right now.

Thoughts On Bill



As you may know, a Tropical Storm, which may soon be a Hurricane, named Bill is churning in the Atlantic, my expected path is above.


I am expecting this to reach category 2, 3, or maybe 4 strengh if the latest models are correct. This will get pushed Northward after a WNW/NW track until the trough gets to it then pushes it northward probally staying off the coast.


Comments would be appreciated.

August 11, 2009 Severe Wx Outlook RYAN

Hi, its Ryan with my new outlook. It says Day 2 as I made it earlier but am posting it now. Enjoy!









I went again with a weird number going 20% wind because the threat will be a good one, but not as good as today. Sorry for using these as the normal level for wind is 5, 15, 30.

The rain outlook is being issued as I received 1.2'' of rain in a strong thunderstorm this evening and the rain and flash flooding threat a lot of times are involved with severe weather. PWAT values do support heavy rains for tomorrow.

August 10, 2009 Verification RYAN

Hi, it is Ryan with a verification update for August 10, 2009. I nailed the storm reports in all of my areas and my greatest threat area was justified. All of the storm reports were in my risk areas and the highest risk areas had the most reports. I think that my greatest risk (25%) should have been extended even more east toward NYC, I think I did a good job with the event.

Grade: 92/100 A.

Tomorrow's Severe and another possibility

Hi, it's Ryan with a SWD. Tonight later has a chance to give the Mid-Atlantic including Baltimore a weakening MCS. More studying will be done or directional patterns but it appears one of the lines is moving south southeast. Also, tomorrow will give us a chance for severe weather, as the GFS and the NAM to some extent have been bullish. I will have a discussion tomorrow morning possibly with a map on this severe weather event.

Here Comes The Heat!













August 9th-11th Heat Potential.

We are going to have some of the warmest Temperatures in the season coming on Sunday, Monday, and Tuesday for the Mid Atlantic, and parts of the Northeast, the culprit is a high pressure area currently situated over are area and a warm front out in the Midwest. This has caused hot weather South and East of the Warm front with high areas of convection near it. This front will be coming this way as we move into the weekend. It will be in the Northeast by Monday causing places South and East to endure hot Temperatures, that includes Temperatures in the 80s, 90s, and maybe even 100s for some. This heat will begin on Sunday, and last until about Tuesday.

Day by day forecast.

Sunday

This will be the start of the heating, the front will be nearing, and we will have the high pressure in the area. This will be giving places in the Mid Atlantic Temps of 90-100 locally while the rest of the Northeast will have Temps of 70-90 degrees, there will be some possible convection with the heat. Here is what I am predicting for Temperatures.

Predicted Highs

Boston:80
Albany:84
New York:86
Philadelphia:90
Harrisburg:89
Baltimore:93
Washington:95
Richmond:97

Monday

This will be the warmest day of the heat, the Warm front will be in place and will allow for major heat for the Mid Atlantic and Northeast, Temperatures in the Mid Atlantic will be 90-105 degrees while the rest of the region will have 75-90 degree Temperatures, there will be more instability and convection around so I wouldn't be suprised if there are Thunderstorms in the Northeast. Heat index may be in the 95-110 degree zone for many in the Mid Atlantic. Here is what I am predicting

Predicted Hights

Boston:83
Albany:86
New York:91
Philadelphia:94
Harrisburg:94
Baltimore:96
Washington:98
Richmond:100

Tuesday

This day will be a little bit cooler in Temperatures due to more convection over the Mid Atlantic and Northeast, but there will still be Above Average Temperatures as the front and the high pressure will still be lingering affecting our weather. I see highs of 90-100 in the Mid Atlantic. especially the eastern part and highs from 70-90 in the Northeast back down through OH, WV, and KY. Here is my prediction for the Temps.

Predicted Highs

Boston:85
Albany:84
New York:88
Philadelphia:91
Harrisburg:91
Baltimore:93
Washington:94
Richmond:96

Overall, this should be the best potential for heat since the June 7-10 2008 Heat Wave. Folks, you should go outside and try to get to the pool as much as possible, also keep your eye to the sky as convection will be high, enjoy this heat while it lasts, with the El Nino, there could be more wild weather ahead.

August 2 Severe Weather Outlook

August Outlook (First post!)

While I agree with Nick's (BTownWeatherWatcher) forecast to an extent, I still decided to make my own, using new software to make the map. Unlike Nick, I foresee an average to below average start in the Northeast, followed by a warm end of the month.

The maps and discussions are shown below.

Temperatures:



Precipitation:


Predicted ENSO value through March 2010


First Winter 2009-2010 Forecast

Here is my first full forecast for the upcoming winter.

First off, the Factors.

ENSO[El Nino Southern Oscillation], the ENSO value lately has been at a Weak El Nino state in most ENSO regions, execpt the NINO 3 region which has a SST values of 1.0, though this still qualifies as a Weak El Nino since Nino 3+4 is still in the Weak El Nino and most of the regions are in a Weak El Nino state. Here is what I am predicting for the SST values through the Winter season. You can see it on the next post.

As you see, I am predicting a Moderate El Nino to form, but it could also stay as a Weak El Nino.

PDO[Pacific Decedal Oscillation], It is currently Negative and I expect it to stay Negative, which stops the El Nino from getting strong.

SOI, It is going negative which should help keep the El Nino Weak to Moderate.

Now, the forecast's.

Temperatures

I expect this to follow a normal El Nino pattern and have mainly Above average Temperatures in the North, and Below average Temperatures in the Southeast, the Northeast could be up for grabs in Temperatures, although I am currently expecting Near average Temperatures.

Rainfall, this should mainly be Below Average in the Northern US, and Above average in the South, Southeast, and potentially the Mid Atlantic, once again the Northeast is up for grabs.

Snowfall, this will be a trickier forecast, it should be Below average in the North, Above average in the east and potentially the Mid Atlantic, the Northeast is up for grabs but it could potentially be Above Average near the coastal areas and 1-95 if, big IF, the storm track falls in their favor.

Storm Tracks, alberta clippers going through the Midwest and the Northeast/Mid Atlantic, bringing light snowfall possible, Gulf of Mexico storms and Miller A storms, we could have a lot of these this Winter due to the active southern jet stream which will carry a lot of moisture, these will bring lots of rain the Southeast and they may ride up the coast if we have a +PNA, which we may have for this Winter, this will be the Mid Atlantic and Northeast's best potential for snowfall this Winter.

So here is my general forecast so far.

ENSO, Moderate El Nino, could be Weak depending on how the PDO, and SOI help.
Temperatures, Above North, Below Southeast
Rainfall, Below North, Above South and Southeast, Mid Atlantic?
Snowfall, Below North, Above Southeast, Mid Atlantic and Northeast?
Storm Tracks, Alberta Clippers and Gulf of Mexico Lows.

Comments would be appreciated.
